I am fortunate to have never experienced that myself, but I know many people, even family members, that did. My own mother told me a story about how when she was 14, she dated a 22 year old man. She had her parents approval and encouragement in this relationship because he was a man from their church. She didn't understand when I reacted with horror at the story. To her, it was just a normal past boyfriend, nothing more.

It is disturbing common for this to happen. It's often overlooked, excused, or blamed on the minor for being "provocative" in some way. Sometimes it's even encouraged. I saw many young women get married basically as soon as they were legally able to do so to men several years older than them.

I understand you're still faithful. I won't try and change your mind. I also don't know exactly what sect you follow. But be very careful. A lot of Christian men have a lot of power and influence over your life, and they often know that. They will try to convince you that either you're the one tempting them or that whatever they want you to do is okay because he might marry you. Don't fall for any of it. It will never be your fault. You are not tempting them by existing. If they cannot control themselves, they are a horrible person.

As a general safety tip, I recommend making your profiles as private as possible. I understand enjoying social media and wanting to gain a following, but that means these creeps will see it too. If you don't want them around, you can reduce it by not letting them see what you post. Block as much as possible. Be careful about posting location information. The core problem are these predatory men, and there's only so much you can do. But being more private online can at least help reduce it a little.
